Setup 2 DVI LCDs, 1 USB keyboard, 1 USB mouse, regular one jack audio.

2 PCs.

I would like to share the peripherals/input devices between the two PCs but so far the dual DVI/USB/Audio KVM I found are super expensive ($200+) if you compare them to simpler 1 DVI head (few $ secondhand, sub $100 new).

What I was thinking is to buy two KVMs instead of one (I understand that I would then need to switch two buttons)

First one would be for peripherals + main LCB Second one would be for the second LCB only.

Would this work? Am I missing something in my understanding of KVMs? I feel like I do cause I certainly don't understand why they cost THAT much.


Because the expensive KVM will unplug the USB devices properly. You can't just let it be used with multiple devices, so it acts like a USB hub as well. You could therefore get away with the less expensive one, then plug a USB hub into the device, or into one computer at a time

  • So assuming I buy a decent KVM or a reg. hub for the USB devices would my idea of two "cheaper" KVM for each DVI port work you think? – jfrobishow Jul 9 '11 at 22:01
  • It'd be a pain, but as long as you know which USB devices are attached to each, you should be fine. Just be warned, don't attach external HDDs with Write Caching – Canadian Luke Jul 9 '11 at 22:34
